Nautilus (the file browser) still has the file open. You will need to
close the nautilus window that was browsing the mounted CD, then re-run
lsof to see if this line has gone.

GAM is a file change monitor. If this doesn't go away when the nautilus
window is closed, you may need to shut down gam manually, by running (as
root) "kill 7765".

Actually the trailing hyphen tells su to use the root user's environment
settings, rather than your own, which is important in this case so the
PATH is set correctly. With or without the hyphen, su allows you to
become root temporarily until you exit the shell.
